Description
Technical field
The utility model relates to a kind of jet flow water distribution distribution device, specifically relates to a kind of BAF jet flow water distribution distribution device.
Background technology
The utility model is " a kind of aeration biological filtering pool water treatment apparatus " (application number: replacement demand 200720052867.7).BAF can be divided into four parts such as water distribution system, gas distribution system, pressure bearing layer, biologic packing material.Airing system two portions when wherein gas distribution system comprises the required aerating system of normal when operation aeration and carries out combined water and air backwash.Keep enough dissolved oxygens in the BAF be keep microbial film high reactivity in the BAF, to the essential condition of the high clearance of organism and ammonia nitrogen, therefore select suitable oxygenation mode very important to the steady running of BAF.Application number is that the disclosed BAF of 200720052867.7 Chinese utility model patents adopts jet-flow aeration, aeration method with respect to routine, it is low to have running cost, the expense of building is few, advantages such as simple are installed, are specially adapted to handle the waste water of very low Organic pollutants load or the processing of micro-polluted source water.But this patent enters the distribute water and air system of BAF after to jet-flow aeration the distribute water and air device is not set, and influences the homogeneity of distribute water and air.
The utility model content
The purpose of the utility model device is to further improving the distribute water and air efficient of BAF, a kind of air water mixing efficiency height is provided, and water-gas distribution is more even, and running cost is low, BAF jet flow water distribution distribution device simple in structure, easy for installation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of BAF jet flow water distribution distribution device comprises ejector, water inlet pipe and hydraucone; Water pump is communicated with successively with ejector, water inlet pipe, hydraucone, and described jet flow water distribution distribution device also comprises reflection cone, and reflection cone is installed in the bottom of BAF, is positioned at bell-mouthed below.
For further realizing the purpose of this utility model, the pipeline that described water pump 1 is communicated with ejector 3 is provided with first valve.
The pipeline that described ejector is communicated with water inlet pipe is provided with second valve.
The pipeline of the negative pressure suction port of described connection ejector is provided with the 3rd valve.
Described reflection cone is a cone shape, and cone angle is the 90-135 degree.
Described reflection cone is by welding, and is bonding, and casting is fixed on the base plate.
Distribute water and air device after the jet of BAF of the present utility model is air-breathing, waste water is carried by water pump, pass through ejector, suck air, the water that is mixed with air is through water inlet pipe, and from the hydraucone ejection, the impact effect awl carries out water distribution and gas distribution, because the setting of reflection cone, this device make BAF air water mixing efficiency height.Entire structure is simple, and is easy for installation, can improve oxygen utilization efficient, effectively reduces working cost.Be specially adapted to the lower BAF of gas-water ratio, as be used to handle the waste water of very low Organic pollutants load or the processing of micro-polluted source water.
The utlity model has following advantage and beneficial effect:
(1) the utility model is by in the BAF bottom reflection cone being set, make air water mixing efficiency height, ejector absorbs air in certain amount, utilize ejector that air water is carried out high efficient mixed, hydraucone by the water inlet pipe end is injected in downwards above the reflection cone of BAF bottom again, the water distribution uniformity gas distribution that makes progress of the reflex action by cone.Make the gas distribution that is blended in the water evenly rise in back, whole aeration and biological bottom, when having avoided direct jet to intake, in bottom, whole filter tank water distribution inequality, cause that small bubbles gather in the water and be air pocket, the problem that causes final total system treatment effect to descend.
(2) the utility model adopts jet-flow aeration, and air water mixes through the hydraucone injection, does not therefore have the easy blocking problem of general perforation distribute water and air pipe, and installation is simple, and not fragile.
Description of drawings
Fig. 1 is a device synoptic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
As shown in Figure 1: novel BAF jet flow water distribution device comprises ejector 3, water inlet pipe 7, hydraucone 8, reflection cone 9.Water pump 1 is communicated with successively with ejector 3, water inlet pipe 7, hydraucone 8, and the pipeline that water pump 1 is communicated with ejector 3 is provided with first valve 2; The pipeline that ejector 3 is communicated with water inlet pipe 7 is provided with second valve 6; The pipeline that connects the negative pressure suction port 4 of ejector is provided with the 3rd valve 5; Reflection cone 9 is installed in the bottom of BAF 10, is positioned at the below of hydraucone 8.Reflection cone is a cone shape, and cone angle is the 90-135 degree, can be by welding, and bonding, technologies such as casting will reflect cone and be fixed on the base plate, and the awl point is relative with hydraucone 8.
When this device is handled waste water, contaminated former water, pending water conservancy pumps into water pump 1, pass through valve 2, ejector 3 successively, simultaneously in the negative pressure suction port 4 of ejector 3, suck air in certain amount, enter the bottom of BAF 10 by valve 6, water inlet pipe 7 and hydraucone 8 again, be injected in by hydraucone 8 and carry out distribute water and air above the reflection cone 9.Regulate the pressure reduction of ejector Inlet and outlet waters by valve 2 and valve 6, thereby adjust the size of ejector, the suction tolerance of regulating ejector negative pressure suction port 4 with valve 5 gas suction.The gas-water ratio that control is fit to for pending water carries out the aerobic reaction degraded in BAF 10, provides only operational conditions, improves the processing efficiency of BAF.
